August 19, 2015 I purchased a license key for Twonky, it worked well but there are some days I tried version 8.2.1 and now I get this message:

this key is already in use by another instance of the server

I deleted all the files and folders named Twonky in my /home as well as the root and then I rebooted the server, I again entered my license key as before and it worked but later again I got the same error message and when I use my media center it tells me that my license has expired

I do not understand what is happening and I would like to get help, thank you in advance
